Japan currently has been successful to provide housing for low to high-income people in urban areas. Almost everyone in Japan can access their homes, either public housing or private one, depending on the level of their welfare status. The study discusses about development of public housing in Japan and why the Japanese people can accept the design of the vertical housing built by their government. The study is conducted with descriptive approach through literature study and field observations in the city of Tokyo and its surrounding areas to provide knowledge about the development of public housing in Japan started from traditional residential and then developed into a modern residential horizontally and vertically according to the needs of his hometown community. Despite of the development from time to time, the design of residence still considers the local culture of Japan. So the Japanese people can receive residential design, although it is developed into vertical housing. This study is expected to give inputs for the Indonesian government as an effort to achieve the successful provision of public housing in Indonesia.

Designing car audio that fits user?s needs is a fun activity. However, the design often consumes more time and costly since it should be consulted to the experts several times. For easy access to information in designing a car audio system as well as error prevention, an car audio system based on expert system and web is designed for those who do not have sufficient time and expense to consult directly to experts. This system consists of tutorial modules designed using the HyperText Preprocessor (PHP) and MySQL as database. This car audio system design is evaluated uses black box testing method which focuses on the functional needs of the application. Tests are performed by providing inputs and produce outputs corresponding to the function of each module. The test results prove the correspondence between input and output, which means that the program meet the initial goals of the design.

Bombings occurred in Indonesia mostly attack high-rise buildings. This fact should be a consideration for the structural engineer when designing high-rise building structures since the design of the structure does not include bomb blast burden in the calculation. This article discusses the dynamic response of buildings with of two plate stiffeners which are then given blast loads. The purpose of this study is to determine the effects of damping and the boom duration of the dynamic response of the plate. The plate is modeled damped orthotropic rectangular with semirigid placement on all sides. A decrease in plate element equilibrium equation is based on moment balance and forces on the plate. Meanwhile, the plate motion equations are derived using Newton's second law. The natural frequency of the plate system is obtained using the Modified Bolotin Method (MBM) as the numerical calculation process is completed with Microsoft Excel 2003 and Mathematica 5.2. Plates will be given damps as much as 0%, 5% and 10%. Each plate with each damp will be given blast loads for 1 ms, 2 ms, 10 ms and 20 ms. The research results shows that the greater the damp is used, the smaller system dynamic response will be. The longer the blast load works, the greater system dynamic response will be.

Forecasting is performed due to the complexity and uncertainty faced by a decision maker. This article discusses the selection of an appropriate forecasting model with time series data available. An appropriate forecasting model is required to estimate systematically about what is most likely to occur in the future based on past data series, so that errors (the differences between what actually happens and the results of the estimation) can be minimized. A gauge is required to detect the required the value of forecast accuracy. In this paper ways of forecasting accuracy of detection are discussed using the mean square error (MSE) and the mean absolute percentage error (MAPE). The forecasting method uses Moving Average, Exponential Smoothing, and Winters method. With the three methods forecast value is determined and the smallest value of MSE and Mape is selected. The results of data analysis showed that the Exponential Smoothing is considered an appropriate method to forecast the sales volume of PT Satriamandiri Citramulia because it produces the smallest value of MSE and Mape.

Executive information system (EIS) has been widely used in enterprises and institutions to help the executives make decisions quickly and accurately for the organization's business needs. A research is conducted to create a marketing executive information system that can produce analytic reports and comparison reports for the executive of Benza Prima. For information search the fact finding techniques is utilized by conducting surveys directly to the company to study the company needs and the running procedures. The executive information system design uses Object Oriented Analysis and Design (OOAD) methodology. The research results in an executive information system that produces report in forms of pivot tables and charts to help the Benza Prima executives make decisions. The marketing executive information system design is expected to provide analytic information that can be used by the Benza Prima executive as an analytic tool in planning marketing strategies.

More online business applications are utilized by companies; one of which is e-procurement. PT Indesso Aroma as a manufacturing company of essential oils, natural extracts, and aromatic chemicals products needs to improve its conventional procurement process to e-procurement to be more effective and efficient. For that, a research is conducted towards the performance and interest of the company's procurement system. Furthermore, the current SAP system application support is developed, as the customer values are analyzed using gap analysis to see the benefits of its application for the company. The e-procurement design uses OOAD method with UML diagram notation including analysis of problem domain, application domain, architectural design and component design. Cost-benefit analysis is performed to see an increase in customer value from the e-procurement application based on measurements of NPV, IRR and ROI of investing in the e-procurement design. Thus an e-procurement application is created that is expected to improve the company?s procurement process with several key features such as Purchase requisition, Purchase Order, Purchase Return, Supplier Catalog and Supplier Quotation.

Companies that have many applications always deal with application integration problems. For the of company necessity, they often yearn for information that an application can be used by other applications. Often a small portion of data from another application is needed in order to complete and support other business functions. They require an architectural approach that can bridge the information between applications. SOA (Service-Oriented Architecture) offers manufacturing services around existing business functions. Applications that wish to communicate with other applications can use the services to achieve business goals. This article will discuss recommendations and tips for implementing SOA best practices in banking.

The increasing number of road user causing traffic jam finds out a way, busway. However, in its implementation, the number of fleet available does not enough to take the passengers. It results in the an amassed of passengers at several bus stops. This leads to passenger dissatisfaction satisfaction which eventually causes Transjakarta users to reuse private cars. Definitely this situation may builds up traffic jams. Stochastic Bus Dispatching Model is used to simulate public transportation that operates regularly.
